Related Art

Currently, when fragile or expensive objects are packaged, the objectsare wrapped in buffer materials first, and then are boxed fortransportation. For an object having a specific shape such as amainboard or a display panel of an electronic device, a buffer materialpackaging structure having a separation trough, such as an extrudedpolyethylene (EPE) material packaging structure, may be further used. Acurrent packaging mode is to prepare two packaging structures with aseparation trough. Firstly, objects such as a mainboard, a display paneland the like are placed into a separation trough of one of the packagingstructures one by one, and the packaging structure only wraps one end ofeach object. Then, the other packaging structure is sleeved on the otherend of the object. The objects are inserted into the separation troughone by one to completely protect the objects, and then the objects areboxed for transportation.

Because a size of the separation trough space is approximately the sameas a size of the objects, the objects can be prevented from moving inthe separation trough, thereby protecting the objects. However, such adesign makes it difficult to insert the objects one by one into theseparation trough when another packaging structure is sleeved on theother end of the objects, resulting in difficulty in assembly.

Refer to FIG. 1 and FIG. 2together. A packaging structure 1 of this embodiment is used foraccommodating and packaging a plurality of objects 9. The objects 9 areobjects to be packaged, and in FIG. 1 and FIG. 2, plate-like objects areused as an example, which may be, but are not limited to, mainboards ordisplay panels of electronic devices. Preferably, the packagingstructure 1 may be a buffer material, such as extruded polyethylene(EPE), to protect the objects 9. The packaging structure 1 of thisembodiment includes an upper cover 10 and a lower cover 20. To describethis embodiment more clearly, two ends of the objects 9 are referred toas first ends 91 and second ends 92 respectively. When the objects 9 arepackaged, the second ends 92 may be placed on the lower cover 20 first,and then, the upper cover 10 may be sleeved on the first ends 91.Details are further described in the following.

FIG. 3A is a schematic diagram of the upper cover shown in FIG. 2, andFIG. 3B is a schematic exploded view of the upper cover shown in FIG.3A. Refer to FIG. 3A and FIG. 3B together. The upper cover 10 includes afirst base plate 11, a first packaging part 12, and a second packagingpart 13 according to this embodiment. The first base plate 11 has afirst folding part 111, and the first base plate 11 is divided into afirst portion 112 and a second portion 113 by the first folding part111, where the first portion 112 is connected to the second portion 113in a foldable manner by the first folding part 111. Specifically, thefirst folding part 111 may be a notch in the first base plate 11 acrossthe first base plate 11, so that the first base plate 11 is divided intothe first portion 112 and the second portion 113 with the first foldingpart 111 as a boundary. In this embodiment, the first base plate 11 is arectangular plate, and the first folding part 111 is parallel to a minoraxis of the first base plate 11. In other embodiments, the first foldingpart 111 may further be parallel to a major axis of the first base plate11, or the first base plate 11 may further be in other shapes. The firstfolding part 111 may be configured so that the first base plate 11 maybe divided into two portions (the first portion 112 and the secondportion 113), which is not limited in the application.

Preferably, the first base plate 11 may be made of the extrudedpolyethylene material so that the first base plate 11 has a thickness T.The first folding part 111 may be a notch in the first base plate 11,and the first portion 112 and the second portion 113 of the first baseplate 11 are still connected to each other. As shown in FIG. 1, a ratioof a depth D of the first folding part 111 (the notch) to the thicknessT of the first base plate 11 may be between 0.25 and 0.75, preferably0.5. For example, the first base plate 11 may be cut with a knife toform the notch (the first folding part 111) to the depth D that is half(0.5 times) the thickness T, or between ¼ and ¾ (0.25 times and 0.75times) of the thickness T. The first base plate 11 may then use thefirst folding part 111 as an axis to fold the first portion 112 or thesecond portion 113. In other embodiments, the first base plate 11 may bepaperboard or other plate-like elements with a buffer property. In thiscase, the first folding part 111 may be a fold line or a cut line.

Preferably, in this embodiment, an area of the first portion 112 issubstantially equal to an area of the second portion 113. In otherwords, a ratio of the area of the first portion 112 to the area of thesecond portion 113 of this embodiment is, for example, 1. In otherembodiments, the area of the first portion 112 may be greater or lessthan the area of the second portion 113, and a manufacturer or a usermay adjust the ratio of the area of the first portion 112 to the secondportion 113 according to needs, which is not limited in the application.

Furthermore, the first packaging part 12 is disposed on the firstportion 112, and the second packaging part 13 is disposed on the secondportion 113. Herein, a surface of the first packaging part 12 that isconnected to the first portion 112 is referred to as a bottom surface,and similarly, a surface of the second packaging part 13 that isconnected to the second portion 113 is also referred to as a bottomsurface. Preferably, an area of the bottom surface of the firstpackaging part 12 is substantially the same as the area of the firstportion 112, and an area of the bottom surface of the second packagingpart 13 is substantially the same as the area of the second portion 113.In other embodiments, the area of the bottom surface of the firstpackaging part 12 may be greater or less than the area of the firstportion 112, and similarly, the area of the bottom surface of the secondpackaging part 13 may be greater or less than the area of the secondportion 113, in other words, the area of the bottom surface of the firstpackaging part 12 (the second packaging part 13) does not necessarilyhave a corresponding relationship with the area of the first portion 112(the second portion 113), and a manufacturer or a user can adjust theratio of the area of the bottom surface of the first packaging part 12(the second packaging part 13) to the area of the first portion 112 (thesecond portion 113) according to needs, which is not limited in theapplication.

In this embodiment, the first base plate 11, the first packaging part12, and the second packaging part 13 are all made of the extrudedpolyethylene material. In addition, the first packaging part 12 and thesecond packaging part 13 of this embodiment are respectively disposed onthe first portion 112 and the second portion 113 in an adhesive manner.As for the manufacturing process, the first packaging part 12 and thesecond packaging part 13 can be separately manufactured, and the firstfolding part 111 is formed in the first base plate 11 by a cutter. Next,the first packaging part 12 and the second packaging part 13, which aremanufactured separately, are respectively adhered to the first portion112 and the second portion 113 of the first base plate 11 to completethe upper cover 10 of this embodiment. In other embodiments, the firstbase plate 11, the first packaging part 12, and the second packagingpart 13 may also be an integral structure. For example, after theoverall structure of the upper cover 10 is integrally formed with theextruded polyethylene material, the upper cover 10 is cut by a cutter toform the first packaging part 12, the second packaging part 13, and thefirst base plate 11 having the first folding part 111 (the notch).

Furthermore, the first packaging part 12 has a plurality of firstseparation troughs 121, and the second packaging part 13 has a pluralityof second separation troughs 131, and positions of the second separationtroughs 131 respectively correspond to the first separation troughs 121,so that the first separation troughs 121 are respectively incommunication with the second separation troughs 131 to form a pluralityof first accommodating slots 14, as shown in FIG. 3A. In other words,the first accommodating slots 14 are composed of the first separationtroughs 121 and the second separation troughs 131. The first separationtroughs 121 and the second separation troughs 131 of this embodiment arestrip-shaped to form the strip-shaped first accommodating slots 14, sothat the first ends 91 of the objects 9 can be accommodated in the firstaccommodating slots 14. In other embodiments, the first separationtroughs 121, the second separation troughs 131 and the firstaccommodating slots 14 formed by the first separation troughs 121 andthe second separation troughs 131 may have other shapes so as toaccommodate the objects 9 of different shapes, which is not limited inthe application. The structure of the lower cover 20 is described in thefollowing, and assembly steps for packaging the objects 9 will bedescribed later.

Referring to FIG. 1 and FIG. 2, the lower cover 20 may have a samestructure as the upper cover 10 in this embodiment, so that the uppercover 10 and the lower cover 20 may be used interchangeably to simplifya manufacturing process of the packaging structure 1. Specifically, thelower cover 20 of this embodiment includes a second base plate 21, athird packaging part 22, and a fourth packaging part 23. The second baseplate 21 is provided with a second folding part 211, where the secondbase plate 21 is divided into a third portion 212 and a fourth portion213 by the second folding part 211, and the third portion 212 isconnected to the fourth portion 213 in a foldable manner by the secondfolding part 211. The third packaging part 22 is disposed on the thirdportion 212, and the fourth packaging part 23 is disposed on the fourthportion 213. It should be noted that a structure of the second baseplate 21 is the same as that of the first base plate 11. For a positionof the second folding part 211 and a distribution ratio of the thirdportion 212 and the fourth portion 213, reference may be made to theforegoing first folding part 111, the first portion 112, and the secondportion 113.

Similarly, the third packaging part 22 has a plurality of thirdseparation troughs 221, and the fourth packaging part 23 has a pluralityof fourth separation troughs 231. Furthermore, positions of the fourthseparation troughs 231 respectively correspond to the third separationtroughs 221, so that the third separation troughs 221 are respectivelyin communication with the fourth separation troughs 231, to form thesecond accommodating slots 24. Furthermore, the third separation troughs221 and the fourth separation troughs 231 are also strip-shaped to formthe strip-shaped second accommodating slots 24, so that the other ends(second ends 92) of the objects 9 can be accommodated in the secondaccommodating slots 24. In other embodiments, the lower cover 20 mayalso be a component that has only a plurality of second accommodatingslots 24 (that is, the lower cover 20 does not have the second foldingpart 211, and does not need to be divided into the third packaging part22 and fourth packaging part 23), as long as the second ends 92 of theobjects 9 can be accommodated in the second accommodating slots 24,which is not limited in the application. The structure configuration ofthe third packaging part 22 and the fourth packaging part 23 may also bethe same as that of the first packaging part 12 and the second packagingpart 13.

FIG. 4A and FIG. 4B are schematic diagrams of actions of the upper coverof FIG. 1 when objects are packaged. Refer to FIG. 4A and FIG. 4Btogether. When the objects are packaged 9, the second ends 92 may beplaced in the second accommodating slots 24 of the lower cover 20, andthen the upper cover 10 is placed over the first ends 91. Firstly, thesecond portion 113 is turned over by using the first folding part 111 asan axis to turn over the second packaging part 13 so that the secondportion 113 is close to the first portion 112 and forms an includedangle, as shown in FIG. 4A. In this case, the first separation troughs121 of the first packaging part 12. are separated from (that is, not incommunication with) the second separation troughs 131 of the secondpackaging part 13, so that a user (a packaging person) or a robot armused for packaging can align the first separation troughs 121 with therespective objects 9, and the first separation troughs 121 of the firstpackaging part 12 are respectively sleeved on one side of the first ends91 of the objects 9, as shown in FIG. 4A, on the right half side of thefirst ends 91. After the right half side of the objects 9 is fixed, theuser or the robot arm can easily turn over the second portion 113 byusing the first folding part 111 as an axis to drive the secondpackaging part 13 to turn over, so that the second separation troughs131 are sleeved on the left half side of the first ends 91 of theobjects 9, and thus, the first ends 91 of the objects 9 are packaged. Inother embodiments, when the lower cover 20 has the same structure as theupper cover 10, a process of placing the second ends 92 in the secondaccommodating slots 24 of the lower cover 20 may be similar to theforegoing process of placing the upper cover 10 on the first ends 91.Details are not described herein.

In summary, the packaging structure according to the applicationincludes an upper cover and a lower cover. The upper cover includes afirst base plate, a first packaging part, and a second packaging part.The first base plate has a first folding part, so that the first baseplate can be divided into a first portion and a second portion. Thefirst packaging part has a plurality of first separation troughs and isdisposed on the first portion; the second packaging part has a pluralityof second separation troughs and is disposed on the second portion. Thesecond portion can drive the second packaging part to turn over by usingthe first folding part as an axis to separate the first separationtroughs from the second separation troughs, and then the firstseparation troughs of the first packaging part are sleeved on first endsof objects. Because the first separation troughs are separated from thesecond separation troughs, the first separation troughs can be alignedwith and sleeved on the objects more conveniently. Then, the secondportion and the second packaging part use the first folding part as anaxis to drive the second packaging part to turn over, so that the secondseparation troughs are also sleeved on second ends of the objects, andpackaging of the objects is completed, so that the effect of convenientassembly is achieved.
